...REMINDER: WE HAVE A NEW WEB ADDRESS...

http://www.genserva.com/acon


  •   NEW WEB SERVER FOR ACON VA/NC/SC    Our old web server has ended the providing of personal webspace which we have used for years. Thus, our files have been migrated to a new commercial server. Our new web address for the group is http://www.genserva.com/acon For members of our group, this means we will be have unlimited space for file storage and we can upload more of your photos to share. Of course, any photos you submit should be weather-related and more significant than just a "pretty picture". However, in the weather field there are just some "pretty pictures" worthy of notice, so submit an occasional "pretty picture" and it may just get posted!!


  • WEATHER IN SPACE?    Although outer space has none of the ingredients we usually think of for weather (moisture and temperatures to sustain life), it can still be a stormy place. The source of the storminess is our sun. The sun, like all active stars, is constantly in motion and often produces eruptions of gas and high energy particles into space (sort of like solar burps). Although solar particles continuously bombard the earth, during a solar eruption the"storm"of particles can be particularly intense. These storms can disrupt communication satellites and power grids on the ground. NOAA's Space Weather Prediction Center monitors and forecasts solar activity so that the effects of solar storms can be mitigated. To learn more about space weather, check out: Space Weather. (notes from the CoCoRaHS website)


  • MEASURING SNOW AND ICE - A REFRESHER    December is a good time of year to take a few minutes to go over how to measure snow and ice. These elements become so much a part of many of our daily lives as we approach the winter solstice. For a comprehensive read on the subject click here: Measuring Snow and Ice. (notes from the CoCoRaHS website)


  • CLIMATOLOGICAL EXTREMES FOR CONTIGUOUS UNITED STATES - 1981-2010    Kevin Shaw of ACON DC/MD/DE sends this link to compilation of extreme statistics for the lower 48 courtesy of his friend Jeff Taylor out in California. View the data here: http://www.wrcc.dri.edu/htmlfiles/state.extremes.html


  • DROUGHT MONITOR    http://www.drought.unl.edu/dm/monitor.html    More information on drought can be found at NOAA's Drought Information Center http://www.drought.noaa.gov/
